- First time booting into CM-11.0 will take a couple minutes
- IMPORTANT NOTES AFTER INSTALLATION:
- Do not delete the “devconf” folder on your micro SD Card as it contains your faux “MACAddress” and “DeviceID”. With a bricked Nook HD+ with no EMMC, the partition containing your device informations are gone. So fake a mac address and serial number will suffice.
- If you know your real device MAC Address, you can replace it with the fake one by editing the “MACAdress” file. Certain routers and modems have a log of devices connected with their mac address that you can use that to pinpoint your real mac address.
- Changing Mac Address:
1. Modify the “MACAddress” file inside the “devconf” folder on your micro SD Card with any 12-digit hexadecimal numbers.
2. Boot into CM 11.0 and turn off your Wi-Fi in the Settings.
3. Open “File Manager“>Settings>Enable “Root Access mode“
4. Browse to and delete /system/etc/firmware/ti-connectivity/wl1271-nvs.bin file.
5. Open up Terminal and type commands,
# sh /system/bin/fix-mac.sh
6. Turn on Wi-Fi.
- Your real Device ID or serial number is located under the micro SD Card cover. You can edit the “DeviceID” file with your real serial number.
- For further informations, please checkout previous post on CM11.0 for Nook HD+. If your device lag too much, change to a difference SDCard.
